copperIn this paper, we study surface atomic structures of etched polycrystalline copper in dilute HCl using contact force mode atomic force microscopy (AFM). The microstructures, i.e. the average grain size, the surface roughness and the section analysis, were investigated before examination at...

Similar to water ice lithography, the instrument for organic ice is specifically designed for gas injection and maintaining low temperatures. Figure18shows the design of an organic ice lithography instrument made by Tiddi et al.58. There were four basic components of this instrument. The most impo...
There are many studies on other transition metal oxide catalysts for ORR, such as cobalt oxides [120], [121], nickel oxides [122], iron oxides [123], copper oxides [124], titanium oxides [125], cerium oxides [126], [127], etc. Among these oxides, Co3O4 is considered to be a pr...
Following this step, the melt was carefully skimmed to remove oxide layers from the surface. Three samplings for chemical analysis were also taken simultaneously at the time of the casting; this was done at the beginning, in the middle, and at the end of the casting process to ascertain the...
a factorial design and analysis of variance on the enzymatic hydrolysis of dilute acid pretreated corn stover showed that high sugar concentrations (130 g/L) have a major inhibitor effect on the enzymatic hydrolysis [88]. To improve the hydrolysis yield, the private sector and academia have studi...
oxide, zinc oxide, nickel oxide, iron oxide, tungsten oxide, copper oxide, and alumina. Along with other metal oxides nanomaterials, TiO2and ZnO have attracted the interest of scientists in wastewater treatment processes. Therefore, nanomaterials have effectively contributed to the establishment of ...
The commonly used materials for wastewater remediation are clay, activated carbon and silica, metal oxides such as titanium oxide, zinc oxide, nickel oxide, iron oxide, tung- sten oxide, copper oxide, and alumina. Along with other metal oxides nanomaterials, T iO2 and ZnO have attracted ...
In the oxidized zones, the main copper minerals are malachite (Cu2CO3(OH)2), cuprite (Cu2O), and azurite (Cu3(CO3)2(OH)2) (Bartlett, 1992). These oxide and carbonate minerals can be leached with dilute sulfuric acid, and copper ores mined from the oxidized zone are generally recover...
